The deionized water used for feeding in our factory must pass through a deoxidation tower. The oxygen capacity in the water after deoxidation is required to be below 1ppm. Nitrogen is introduced from the bottom of the tower and deionized water is introduced from the top for replacement. Currently encountering a puzzle: After the car was parked during the Spring Festival last time, I changed the nitrogen flow rate to 70nm3/hr when I came back to drive. As a result, the deoxygenation effect became very bad, and the oxygen capacity reached 3.5ppm. When I changed the nitrogen flow rate back to 40nm3/hr, it returned to normal 0.5ppm. I am puzzled, and I would like to ask you for advice :P
What kind of tower is it? Packed tower, sieve plate tower or robe tower? It is estimated that the excessive gas velocity caused "liquid flooding".
Ask the landlord: Which manufacturer makes your degassing tower? Now our company also needs to install a deionized water deoxygenation tower.
